I am glad to see you working on this set. I have a model 4563 Silvertone radio that I bought at a flea market back in the mid 70's when I was about 10-12. It has the same gold dial as yours and the knob arrangement is the same with all of the same knobs yours has except mine has the correct volume knob. From what I can find it was made in 1936 by a company called Colonial radio for Sears. I don't know how accurate that information is. I was lucky because the correct schematic was glued to the side of the chassis. The tube compliment of the chassis in mine is 6A7, 6D6, 6H6G, 6F5G, 6B5, 80. Unfortunately it was the radio I learned to fix tube electronics on. It got modified and experimented on and somehow survived all of that. I restored the circuitry back to original configuration about 10 years ago when I tried it out and it no longer worked because some of the wax capacitors had opened up. The caps in mine looked more like flat crayolas than what was in yours. I found another chassis for mine on eBay since the dial on mine was slightly corroded. This chassis had the same tube lineup as yours. My assumption was a number of different chassis were made to the same dimensional spec so they would all fit the different cabinets. Of course the replacement chassis had a dial that was messed up in a different way. The seller must have taken the pics with a potato, but that is eBay for you. At least it was cheap.
Silvertone was a Sears brand name, not a manufacturer thus sears would use different contract manufacturers for sets with the same model number.. They were often entirely different chassis. Apparently Sears specified or maybe even supplied the cabinets and gave the same model number based on the cabinet style.. Later sources of schematics often did not take this into account and it is often difficult to find the correct circuit.
Very interesting project Vern and it looks like an earlier design than 1937, maybe resurrected to flog off to Sears. Having said that, I worked on a 1940 radio with volume control still in the antenna circuit. Is that a wilhelm scream I hear 😄 Can you elaborate on the three gang tuner and no RF stage in a future video, I didn't quite get what you were saying, sorry.
I just sent you an email with the schematics. I was totally befuddled by the fact that the schematic in the radio was not the correct one. Took quite a while to figure out the correct search terms to finally find the correct one. Model number search did not return correct results.
Yikes! But I think I noticed that in the schematic with the grid having a DC path to ground via the volume pot that there was a 250Ω cathode bias resistor. Could be wrong of course.
